Yokohama City: Mayor Fumiko Hayashi

In the increase of expectation toward cities globally due to the adoption of the Paris Agreement at COP21, Yokohama promotes decarbonization targeted at the goal "Zero Carbon Yokohama". Yokohama focuses on sustainable urban planning including global warming mitigation as a SDGs FutureCity designated by the Japanese Government.

Yokohama has been solving urban problems in liaison with other cities both inside and outside of Japan, and international organizations. We would like to realize a sustainable society by sharing knowledge and collaborating, together with ICLEI member cities actively.

Overview of Yokohama City


Population: 3,747,967 (as of May 1, 2019)

Yokohama is a beautiful international port city located in the greater Tokyo area. It is full of diverse attractions, including not only the modern waterfront symbolized by Minato Mirai 21 but also expanses of residential districts in the suburban areas covered with rich green and agricultural land.

The opening of Yokohama as a port to the world in 1859 triggered its subsequent development. Since then, Yokohama has developed into the nation’s second largest city with a population of 3.7 million by overcoming various difficulties such as the Great Kanto Earthquake, rapid population growth, and environmental pollution. The know-how and technical prowess in city administration developed in this process provides the foundation for its contribution to the international community today. In recent years, the city has hosted many international meetings such as Asian Development Bank Annual Meeting, Tokyo International Conference on African Development (TICAD). In addition, a total of 34.20 million tourists visited the city in 2018. Thus Yokohama is also strong in attracting tourism and MICE events.

Environmental initiatives

Yokohama City has taken leadership in implementing measures to mitigate global warming such as power saving, energy conservation, and expansion of renewable energy use. We refined "Yokohama City Action Plan for Global Warming Countermeasures" in October, 2018 and conduct it aiming at the higher goal of "achieving decarbonization as early as possible in the later of this century" looking at 2050 under the slogan of "Zero Carbon Yokohama". For example, we are creating a chain of action for global warming countermeasures through "All-Yokohama" efforts: introducting new technology in cooperation with businesses, maximizing smart usage of renewable energy in liaison with other local governments, and activities by citizens. As a SDGs FutureCity designated by the Japanese Government, we have established Yokohama SDGs Design Centre and are engaged in communicating solution models toward urban problems such as global warming and aging population.
